 DETAILED DESCRIPTION
To make the skilled in the art better understand the technical solutions of the present application, the present disclosure will be described clearly and completely hereinafter in conjunction with the drawings and the embodiments. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all embodiments. Based on the embodiments in the present disclosure, all other embodiments, obtained by the skilled in the art without any creative efforts, fall within the scope of protection of the present disclosure.
A program upgrade method is provided in the present disclosure. The program upgrade method is applied to a TWS headphone. In the present disclosure, the TWS headphone is paired with a terminal device (such as a computer, a smart phone, a tablet, a smart watch, etc.) through a wireless communication protocol (such as Bluetooth) for data transmission. The TWS headphone further includes a headphone charging box used in conjunction with the headphone. The headphone charging box is provided with a cavity inside for containing the headphone, and the headphone charging box is configured to charge the wireless headphone when the headphone is placed in the cavity.
The TWS headphone includes a first wireless headphone and a second wireless headphone arranged in pairs. The first wireless headphone and the second wireless headphone together may form a pair of TWS headphones. The first wireless headphone and the second wireless headphone are configured to output audio to a left ear and a right ear respectively. The “first” in the first wireless headphone and the “second” in the second wireless headphone are not specifically limited, and are only used for distinction.
Reference is made to FIG. 1, which is a flow chart of a method for upgrading a program of a TWS headphone according to the present disclosure. The method includes following steps S101 and S102.
In step S101, a wireless communication connection between the first wireless headphone and a terminal is established, and a first upgrade file sent by the terminal for upgrade is received by the first wireless headphone.
In step S102, a wireless communication connection between the second wireless headphone and the terminal is established, and a second upgrade file sent by the terminal for upgrade is received by the second wireless headphone after the first wireless headphone completes upgrade.
The process of establishing the wireless communication connection between the second wireless headphone and the terminal may be performed before, at the same time or after the terminal sends the first upgrade file to the first wireless headphone. The execution order of the process of establishing the wireless communication connection between the second wireless headphone and the terminal will not affect the implementation of the present disclosure, and thus it is not limited herein. As a specific implementation, in this embodiment, after the first wireless headphone completes upgrade, the wireless communication connection between the first wireless headphone and the terminal may be disconnected, and then the wireless communication connection between the second wireless headphone and the terminal may be established, to upgrade the second wireless headphone.
It should be noted that, in the present disclosure, the first upgrade file received by the first wireless headphone and the second upgrade file received by the second wireless headphone may be a same upgrade file, or, they may also be different upgrade files, which are not limited herein.
In the program upgrade method according to the present disclosure, the TWS headphone includes the first wireless headphone and the second wireless headphone arranged in pairs; upon upgrading, the wireless communication connection between the first wireless headphone and the terminal is established, and the first wireless headphone receives the first upgrade file sent by the terminal for upgrade; the wireless communication connection between the second wireless headphone and the terminal is established, and after the first wireless headphone completes upgrade, the second wireless headphone receives the second upgrade file sent by the terminal for upgrade. Therefore, the two headphones are upgraded separately through the terminal, and there is no need of a communication connection between a master headphone and a slave headphone for transmitting upgrade data, thereby avoiding upgrade failures due to unstable connections between the two headphones and improving the reliability of an upgrade operation. Furthermore, in the present disclosure, there is no need for the master headphone to implement a series of processes such as storing upgrade data firstly, reading upgrade data, and forwarding upgrade data to the slave headphone, that is, the master headphone does not need to transfer data. Thus, the upgrade time is saved, and on the other hand, consumption of resources of the master headphone occupied by transferring data are avoided since the master headphone is not required to perform operations such as storing and reading data.
The wireless communication connection between the terminal and the wireless headphones may be established by means of Bluetooth, or by means of other wireless methods. Taking the first wireless headphone as an example, a detailed implementation of establishing a wireless communication connection in the present disclosure will be illustrated hereinafter. Reference is made to FIG. 2, which is a flow chart illustrating a process of establishing a wireless communication connection according to the present disclosure. The process includes following steps S201 and S202.
In step S201, an upgrade instruction is received by the first wireless headphone, an upgrade response information for entering an OTA mode is generated, and the upgrade response information is sent to the terminal.
Specifically, the upgrade instruction received by the first wireless headphone may be sent by the terminal directly, or may be sent by a headphone charging box of the TWS headphone. FIG. 3 illustrates a detailed process in a case that the upgrade instruction is sent by the headphone charging box of the TWS headphone, which includes the following steps S2011 and S2012.
In step S2011, in a case of detecting a preset event by the headphone charging box, the headphone charging box performs a BLE broadcast, where a broadcast field includes a field for notifying the headphone to prepare to enter the OTA mode.
The preset event may be a long-press operation on a preset button of the headphone charging box. The wireless communication method in this embodiment may be the BLE broadcast (Bluetooth Low Energy Technology) method, or other methods such as a traditional Bluetooth method, which are not limited herein.
In step S2012, in a case of detecting, by the headphone charging box, that the first wireless headphone is placed at a first preset position, the first wireless headphone executes an OTA code segment and performs a wireless communication scanning; and generates the upgrade response information for entering the OTA mode when an OTA signal is scanned by the first wireless headphone within a preset time period.
Reference is made to FIG. 4, which is a flow chart illustrating a process of putting a headphone into a headphone charging box. The process may include the following steps S1 to S4.
In step S1, an OTA code segment is executed and a BLE scanning is performed, when the headphone is placed in the headphone charging box.
In step S2, it is determined whether preparation for OTA times out. If it is determined that the preparation for OTA times out, a normal operation mode is entered; and if it is determined that the preparation for OTA does not time out, proceed to step S3.
In step S3, it is determined whether an OTA instruction is scanned. If it is determined that the OTA instruction is not scanned, return to the step S2; and if it is determined that the OTA instruction is scanned, proceed to step S4.
In step S4, the OTA mode is entered, and an upgrade process is prepared.
The process of notifying the headphone whether to enter the OTA mode by the headphone charging box may be implemented by extending an OTA scanning of a conventional headphone charging box, without additional development settings on a mobile phone side, which is convenient for development. Moreover, the headphone is placed in the headphone charging box during an entire upgrade process, thus avoiding upgrade failures due to insufficient power and ensuring the stability of charging.
In step S202, the upgrade response information is received by the terminal, and a BLE wireless communication connection with the first wireless headphone is established.
Further, the method according to an embodiment of the present disclosure may further include a step of disconnecting, by the first wireless headphone, the BLE wireless communication connection with the terminal after the first wireless headphone completes upgrade. Similarly, the BLE wireless communication connection between the second wireless headphone and the terminal is disconnected after the second wireless headphone completes upgrade. In this way, it may avoid power consumption of the two headphones due to continuous communication, and on other aspect, it may prevent other settings from stealing important information through the connection, thereby ensuring the security of communication. After the second wireless headphone completes upgrade, the method further includes: sending an upgrade completion instruction to the terminal, for the terminal to prompt an information display item indicating that an upgrade operation is completed and prompt an operation display information about disconnecting the BLE broadcast of the headphone charging box. Thus, it may avoid the headphone charging box being in a continuous power consumption state, thus to save energy.
In addition, a method for upgrading a program of a TWS headphone is further provided in the present disclosure, where the TWS headphone includes a first wireless headphone and a second wireless headphone arranged in pairs. The method is applied to a terminal, and may be implemented by combining software and hardware of a terminal. As shown in FIG. 5, the method includes the following steps S301 and S302.
In step S301, a wireless communication connection between a terminal and the first wireless headphone is established, and a first upgrade file for upgrade is sent to the first wireless headphone through the terminal.
In step S302, a wireless communication connection between the terminal and the second wireless headphone is established, and a second upgrade file for upgrade is sent to the second wireless headphone through the terminal after the first wireless headphone completes upgrade.
It should be noted that, the method for upgrading a program of a TWS headphone provided in the present disclosure corresponds to the program upgrading method applied to the TWS headphone described above. Specific implementations thereof may refer to the aforementioned process, which will not be repeated herein.
On a basis of any one of embodiments described above, before the step of establishing the wireless communication connection between the terminal and the first wireless headphone and sending the first upgrade file for upgrade to the first wireless headphone through the terminal, the method further includes:
outputting an option for prompting whether to upgrade, in response to detecting, by the terminal, that a program version in a cloud has been updated; and
receiving an option instruction for performing a program upgrade, and prompting an operation instruction information for starting the program upgrade.
In this embodiment, when the terminal detects that the program version in the cloud has been updated, an option about whether to upgrade may be prompted to a user on a human-computer interaction interface. If the user confirms to perform an upgrade, an option instruction for performing a program upgrade is inputted to the human-computer interaction interface. After receiving the option instruction, the human-computer interaction interface displays an operation instruction information on some operations to be performed during the program upgrade process, for example, displays an information of “please put the left headphone in the corresponding position” or the like to instruct the user how to operate. Through the human-computer interaction process in this embodiment, the upgrade process is performed more humane, and the user experience is improved.
Referring to FIG. 6, taking the terminal specifically as a mobile phone as an example, a method for upgrading a program of a TWS headphone according to the present disclosure is illustrated hereinafter. The method includes the following steps S401 to S407.
In step S401, an option for prompting whether to upgrade is outputted when a mobile phone detects that a program version in a cloud has been updated.
When the mobile phone detects a new program version update in the cloud, the mobile phone prompts a user whether to upgrade, for the user to select whether to upgrade. If the user confirms to upgrade, the subsequent upgrade process is performed.
In step S402, an option instruction for performing a program upgrade is received by the mobile phone, to prompt an operation instruction information for starting the program upgrade.
When the user selects the option instruction of “upgrade”, that is, when the user confirms to perform an upgrade operation, prompt information indicating which operations the user needs to perform may be displayed on the mobile phone. For example, the prompt information may be “trigger a preset event on the headphone charging box, and put the headphone to be upgraded in a preset position”.
In step S403, the headphone charging box performs a BLE broadcast in response to detecting a preset event, where a broadcast field includes a field for notifying the headphone to prepare to enter the OTA mode.
The preset event may be an event of detecting that the headphone is taken out of the headphone charging box and the time duration that a preset button on the headphone charging box being triggered exceeding a preset threshold (e.g., 10 s). If the preset event is detected, the BLE broadcast is performed. The broadcast information includes a field for notifying the headphone to enter the OTA mode. At this time, the mobile phone prompts the user to put the first wireless headphone into the headphone charging box, and the user follows the prompt to put the first wireless headphone into the headphone charging box.
In step S404, the first wireless headphone executes an OTA code segment and performs a wireless communication scanning in a case of detecting that the first wireless headphone is placed at a first preset position of the headphone charging box; the first wireless headphone generates an upgrade response information for entering the OTA mode when an OTA signal is scanned within a preset time period; and the first wireless headphone sends the upgrade response information to the mobile phone.
The first wireless headphone may execute the OTA code segment after being placed in the headphone charging box. The first wireless headphone may exit the OTA preparation mode if timeout, and enter a normal operation mode. A BLE scanning will be performed at regular intervals until timeout. If an OTA instruction is scanned, an upgrade operation is performed on the first wireless headphone, that is, when the OTA instruction is received, a message indicating that an upgrade operation is ready will be broadcasted through BLE.
In step S405, the mobile phone establishes a BLE wireless communication connection with the first wireless headphone upon receiving the upgrade response information, sends a first upgrade file for upgrade to the first wireless headphone, informs the mobile phone of completion of upgrade, disconnects the BLE connection with the mobile phone, and enters a normal operation mode.
After receiving the upgrade response information, the mobile phone establishes the BLE connection with the headphone and sends the upgrade file to the headphone. The headphone receives the upgrade file and performs an upgrade operation. After completion of upgrade, the headphone informs the mobile phone and disconnects the BLE connection with the mobile phone.
In step S406, a wireless communication connection between the mobile phone and the second wireless headphone is established, a second upgrade file for upgrade is sent to the second wireless headphone through the mobile phone. After completion of upgrade, the second wireless headphone informs the mobile phone, disconnects the BLE connection with the mobile, and enters a normal operation mode.
An upgrade process of the second wireless headphone is the same as the upgrade process of the first wireless headphone.
In step S407, after the two headphones both complete upgrade, the mobile phone prompts the user to perform an operation of exiting the BLE broadcast mode on the headphone charging box, to end the upgrade process.
The program upgrade process of a TWS headphone described above may be divided into three stages: a preparation stage, a first wireless headphone upgrade stage, and a second wireless headphone upgrade stage.
In the preparation stage, the mobile phone prompts the user whether to upgrade in response to detecting a new software version in the cloud. If the user selects an option instruction of “upgrade”, takes all headphones out of the headphone charging box according to the prompt of the mobile phone, and presses a button of the headphone charging box for 10 s to make the headphone charging box perform the BLE broadcast. The broadcast information includes the field for notifying the headphone to enter the OTA mode. At this time, the mobile phone prompts the user to put the first wireless headphone into the headphone charging box, and the user follows the prompt to put the first wireless headphone into the headphone charging box.
In the first wireless headphone upgrade stage, the first wireless headphone may execute the OTA code segment after being placed into the headphone charging box. The first wireless phone may exit the OTA preparation mode if timeout, and enters a normal operation mode. A BLE scanning will be performed at regular intervals until timeout. If an OTA instruction is scanned, an upgrade operation is performed on the first wireless headphone, that is, when the OTA instruction is received, a message indicating that an upgrade operation is ready will be broadcasted through BLE. After receiving the message, the mobile phone establishes the BLE connection with the headphone and sends the upgrade file to the headphone. The headphone receives the upgrade file and performs an upgrade operation. After completion of upgrade, the headphone informs the mobile phone and disconnects the BLE connection with the mobile phone.
In the second wireless headphone upgrade stage, the upgrade process of the second wireless headphone is the same as the upgrade process of the first wireless headphone.
After the two headphones both complete upgrade, the mobile phone prompts a message of “upgrade completion” to the user, and prompts the user to press the button of the headphone charging box for 10 s, to make the headphone charging box exit the BLE broadcast. At this time, the OTA mode is finished.
According to the method for upgrading a program of a TWS headphone provided by the present disclosure, the two headphones are successively notified to enter the OTA mode through the headphone charging box, and the two headphones are successively upgraded through the mobile phone. The first wireless headphone may be a left headphone, and the second wireless headphone may be a right headphone. Of course, the upgrade sequences of the two headphones may be interchanged, which will not affect the implementation of the present disclosure. Since the two headphones are upgraded respectively through the mobile phone, the time required for the upgrade process is saved, and the reliability of the upgrade operation is improved.

The two wireless headphones in the present disclosure are upgraded respectively through the terminal, without upgrade data transmission through a communication connection between a master headphone and a slave headphone, thereby avoiding upgrade failures due to unstable connections between the two headphones and improving the reliability of an upgrade process. Furthermore, there is no need for the master headphone to implement a series of processes such as storing upgrade data firstly, reading upgrade data, and forwarding upgrade data to the slave headphone, that is, the master headphone does not need to transfer data. Thus, the upgrade time is saved, and on the other hand, consumption of resources of the master headphone occupied by transferring data is avoided since the master headphone is not required to perform processes such as storing and reading data.
